Simplify the expression. First, distribute 15 to all terms within the parenthesis
15(3 + 5x) + 25
15(3) = 45
15(5x) = 75x
45 + 75x + 25
Simplify. Combine like terms
75x + (45 + 25)
75x + 70
-------------------------------------------------------------------------------------------------------------------
75x + 70 is your simplified expression.
hope this helps
